rings of Saturn [′riŋz əv ′säd·ərn] (astronomy) Circular rings that encircle the planet Saturn at its equator; there are four main regions to the ring system; theory and observations indicate that the rings are composed of separate particles which move independently in the four series of circular coplanar orbits.

| NEW MOON--The Cassini spacecraft recently confirmed the existence of a 7-kilometer-wide moon, provisionally named S/2005 S1 (arrow), in a section of the outer part of the A ring known as the Keeler gap. Although the moon is only 7 kilometers across, it has enough gravity to scallop the edges of what's known as the Keeler gap in the A ring, the outermost of the planet's bright main rings. |
